IMPROVEMENT IN CARPET-FASTENERS.

Specification forming part of Letters Patent No. 203,209, dated April 30, 1878; application filed November 17, 1877.

To all whom it may concern:

Be it known that I, DAVID F. STAMBAUGH, of Casey, in the county of Clark, and in the State of Illinois, have invented certain new and useful Improvements in Devices for Attaching Carpets to Floors; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction of a device which is attached to thebase-board in a room for the purpose of acting upon a strip to form acarpet-holder, as will be hereinafter fully set forth.

To enable those skilled in the art to make and use my invent-ion, I will proceed to describe its construction and operation.

In the accompanying drawing, Figure 1 is a perspective of my invention, and Fig. 2 is a section of the concavo-convex strip.

A represents the base-board in a house. B represents the floor, and G the carpet upon the floor.

Placed upon the carpet, near its edge and near the base-board, is a concavo-convex strip,

d, and secured to the base-board, above this strip, is a lever, c. This lever e is pivoted to the base-board, as represented, and is provided with a wing, at, which is either concavo-convex, or'concave on its under side,-to fit the upper side of the strip d.

When the free end of the lever is raised it describes the curve seen in dotted line, and

the wing at is elevated, so that it frees the strip d.

. In using this device the free end of the lever is first raised the carpet is then stretched, the strip is placed in position, and then the lever is turned down so that its wing at rests upon the strip, and clamps it securely in place, and thus holds the carpet from drawing or moving.

The strip d, being concavo-convex, is in a measure flexible, and its edges'are feathered, and only bear on the carpet, and the strip will spring or yield not only to the pressure of the fastening device, but also to the strain of the carpet, but atthe same time hold the carpet firmly in its place.

I do not broadly claim a concavo-convex strip, nor do I broadly claim a lever provided with a wing pivoted to the wash-board, as I am aware that such devices, taken separately, are of themselves not new.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

The combination of the flexible metallic concavo-convex strip d, having feathered edges as m, with the pivoted lever 6, having forwardlyprojecting curved wing at, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of October, 1877.
